Canaccord Adams analyst Peter Misek believes there is “a good chance” that Apple is going to announce the iPhone 4G loaded with OS 4.0 on Verizon on it’s upcoming event on Wednesday 27th.

“Together with our semi-conductor partners, we have ascertained that there is a reasonable chance the Asian supply chain is prepping for mass production of a new iPhone in March, for availability in late Q2, likely June,” Misek wrote in a note to clients today.

“The phone will be carried on Verizon and hence will operate on the CDMA network; however, it will also support European GSM and HSPA standards. An updated 4GS version that will support LTE is anticipated to arrive in June 2011. At this moment, we have not heard about the pricing of the device, but believe it will be different from what it is at the moment. While we remain of the view that tiered data plans are imminent, our checks indicate the new iPhone from Verizon will still come with an unlimited data plan.”

Earlier rumors says that Apple will announce Tablet and iPhone OS 4.0. But after this one, do you believe that Apple is going to unveil two iDevices on a single event loaded with brand new iPhone firmware 4.0?
